Ko te tauira whaipainga e pa ana ki te waahi hangarau o te taputapu hurihanga catalytic ternary mo te purenga hau hiku o te motuka motuka, ina koa ki te kawe whakarewa o te kaitahuri catalytic ternary. Ka whakatauhia e ia nga raru hangarau penei i te hoahoa koretake o te hangarau o naianei.
Ko te kaikawe whakarewa o te kaitahuri catalytic ternary he anga o te rango me tetahi matua kua whakaritea ki roto i te anga, e tohuhia ana ko te matua kei roto He maha o nga pereti kua whakaritea kia whakarara tetahi ki tetahi me te mokowā rite, me te pereti piko i te ahua ngaru. kua whakaritea i waenganui i nga papa e rua e tata ana. Ina whakaritea ki te hangarau o naianei, ko nga painga o te kaikawe whakarewa o te kaitahuri catalytic ternary e whai ake nei: He whaitake te hoahoa, he maamaa te hanganga, he roa te oranga o te ratonga, he iti te utu o te hangahanga, he pai te pumau o te mahi.
Ka taea e matou te whakarato i nga taputapu whakarewa e rua kua whakakikoruatia ki nga konganuku rangatira o Pt, Pd, Rh me te kore he konganuku rangatira, ka taea te whakatutuki i te paerewa tuku Euro II, Euro III, Euro IV, Euro V, EPA me CARB.
